Frequently Asked Questions

What is the OSG spiral point tap #12-28 UNF used for?

This OSG spiral point tap is used for threading through-holes in metal, steel, and aluminum. Its spiral point design pushes chips forward, preventing clogging. It is ideal for automotive, aerospace, and general manufacturing applications requiring precise UNF threads.

What are the specifications of the OSG tap MPN 2809201?

The OSG spiral point tap MPN 2809201 has a #12-28 UNF thread size, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general purpose tap designed for through-hole threading. 3G Electric supplies this OSG tap globally.

Where to buy OSG taps in worldwide?

You can source OSG taps worldwide through 3G Electric. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial distributor since 1990, we provide OSG taps like the #12-28 UNF spiral point tap to customers across industries.

How to select the correct OSG tap for a threading job?

Select an OSG tap based on thread size, pitch, and material. For through-holes, use a spiral point tap like the #12-28 UNF. Match the tap tolerance (e.g., H3) to the required thread class (2B or 3B). Consult OSG's technical data for optimal speeds and lubrication.
